Buffalo Bills defensive tackle Marcell Dareusannounced Saturday that he intends to enter a rehabilitation facility following news of his most recent suspension for violating the NFL’s substance abuse policy.

“After careful consideration of recent events within my life, I have made the decision to enter a rehabilitation facility,” Dareus said in a statement released through the team. “I feel this is the best decision for me, my family and my teammates as I move forward with my career. I appreciate the support of my teammates and the Bills organization through this process.”

Dareus’ four-game ban, announced earlier this week, marks the second time in as many years that he’ll be forced to start the season on the sidelines. His first violation of the league policy landed him a one-game suspension to open the 2015 campaign.

The Bills followed up news of the latest punishment with a stern public message, characterizing the defensive tackle’s behavior was “unaccaptable” and expressing disappointment that he put himself before the rest of the organization.
